OIL-STOVE.

SPECIFICATION forming part of Letters Patent No. 723,499, dated March 24, 1903.

Application filed October 13, 1902.

To all whom it may concern.-

Be it known that I, OREN TEACHER, a citizen of the United States of America, residing at Chelsea, in the county of Washtenaw and State of Michigan, have invented certain new and useful Improvements in Oil-Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in oil-stoves; and its object is to provide cheap, simple, and efficient means for accelerating the extinguishment of the flame of oil-burners which are turned out by cutting off the supply of oil; and to this end the invention consists in inserting in the supply-pipe a combined feed and discharge valve,whereby when the valve is turned to cut off the supply the oil within the burner will be drawn 0E through the discharge-passage of said valve, so that the flame will not be maintained after the supply has been cut off, but will go out at once.

The invention also consists in so attaching a receiving-tank to said valve that when the valve is turned. to cut 0E the supply the oil in the burner will flow into said receivingtank and when turned to supply the burner said receiving-tank will be raised above the level of the burner to cause the oil to flow back to said burner; and it further consists and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in which Figure 1 is a transverse vertical section of an oil-stove provided with a device embodying my invention, which is shown partially in section; and Fig. 2 is an enlarged view of the device detached, showing the same in vertical section on a line at rightangles to that of Fig. 1.

I have shown my invention applied to an oil-bu rning stove of well-known construction, in which A is the frame; 13, the burner, provided with an annular groove B to receive the stationary wick C.

D is the oil-supply pipe, secured to the frame A and extended upward beneath the burner, to the upper end of which pipe said burner is secured by a casting having arms connected with the annular groove B of. the

Serial No. 127,029- (No mode burner and formed with conduits to conduct oilfrom the supply-pipe to the wick, and supported at the side of the frame is a supplytank E, provided with a reservoir E, to which the supply-pipe D is connected, and with a valve E which operates within the reservoir, on the principle of a student-lamp, to maintain the oil at a certain height in the burner.

As ordinarily constructed a stove of the character described has an ordinary feedvalve or needle-valve interposed in the supply-pipe to stop the flow of oil to the burner when it is desired to extinguish the flame; but cutting off the supply of oil will not at once put out the flame, as there will be sufficient oil contained in the burner to maintain the flame for some time. I therefore interpose in the supply-pipe in lieu of the ordinary feed-valve the combined feed and discharge valve F, which is provided with the plug F, having a transverse passage F -adapted to register when the plug is in one position with the passage F in the valve-casing to form a continuous feed-passage for the oi l through the supply-pipe, and a passage F leading outward through the side of the plug in a direction at right angles to the passage F, is adapted to connect the part of the supply-pipe above the valve with a dischargepassage F extending longitudinally of the plug from the passage F outward through the stem G of the plug, which stem is a tube formed integral with the plug or secured thereto, as desired. This tubular valve-stem G is bent at right angles a short distance from the valve, and to its outer upturned end G is secured a small receiving-tank H to receive the oil from the burner, which oil will pass downward through the passage F and outward through the d ischarge-passage and tubular stem when the plug is turned to the position shown in full lines in Fig. 2.

The passages in the plug are so arranged with relation to the direction in whichthe portion G of the tubular stem extends that when the plug is positioned so that the supply-tank where all the oil contained in the burner and supply-pipe above the valve will flow into it. When the plug is in the position shown in Fig. 1, it will be seen that the tank H is above the oil-level maintained in the burner, and

as the passage F is connected with the passage F the oil in the tank which was previously drawn from theburner and supply-pipe will fiow back into said pipe to the burner.

In order that all of the oil may be drained from the supply-pipe above the valve, and to allow for a vent-hole I in the top of the tank H, the tubular stem is attached to the bottom of the receiving-tank, near one side thereof, so that when the tank is turned down the tube will be connected thereto near the side thereof which is uppermost.

It is obvious that instead of the arrangement of receiving tank and the passage throughthe stem the oil might be drawn from the burner through a passage and pipe leading to any suitable vessel; but this construction is preferred, as it obviates the necessity of returning to the supply-tank the oil drawn off and is cheap and convenient, the tubular stem serving as a handle to turn the valve, and by raising the receiving-tank above the level of the oil in the burner the oil in said tank is given considerable head and will rise more quickly to the burner.

From the foregoing description it will be readily seen that the purpose and operation of this device is very different from that shown in Patents No. 435,272, of August 26 1890, and No. 701,475, of June 3, 1902.

Having thus fully described my invention, what I claim is 1. Inan oil-stove the combination with a burner, an oil-supply tank, and a feed-pipe connecting the burner and tank; of a valve inthe feed-pipe, and a receiving-tank adaptedtobe lowered to draw oif the oil from the burner when the valve is turned to stop the flow from the supply-tank to the burner and to be raised to cause the oil drawn from the burner to flow back to said burner.

2. In an oil-stove, the combination witha burner, an oil-supply tank, and a feed-pipe connecting the burner and tank; of a comwaits above the burner to cause the oil contained in said tank to flow to the burner.

3. In an oil-stove, the combination with a burner, an oil-supply tank, and a feed-pipe connecting the burner and tank; of a combined feed and discharge valve in said feedpipe and provided with a plug having a discharge-passage, a tubular stem on said plug communicating with the discharge-passage and bent at right angles intermediate its ends to extend vertically when the plug is turned to open the feed-passages and to extend horizontally when the plug is turned to open the discharge-passage,and a tank secured to the outer end of said tubular stem.

4. In an oil-stove, the combination with a burner, anv oil-supply tank, and a feed-pipe connecting the burner and tank; of a combined feed and discharge valve in said feedpipe and provided with a plug having a feed and a discharge passage, a tubular stem on the plug into which the discharge-passage opens, said stem being bent at right angles to extend vertically when thefeed-passage is open and to extend horizontally when the plug is turned to close the feed-passage, a receiving-tank secured on the end of said stem with the stem opening into the bottom of said tank near one side thereof, whereby thestem is turned and the tank lowered, said stem will discharge the oil into said tank near the side thereof which is uppermost.

In testimony whereof I affix my signature in presence of two witnesses.
